To all whom it may concern: 7

Be it known that I, ADRIAN DENMAN- Jones, a subject of the King of Great Britain, residing at 37 Hartham road, Holloway, in the county of London, England, have invented a-r new and useful Improvement in Heating Devices for Automobiles, of which .the following is a specification.

This invention relates to improved means for warming automobiles.

It has before been proposed to warm an automobile by leading hot air from around the engine through a heater in the automobile. This arrangement has the defect that the circulation'of the air through theheater;

being dependent upon the motion of the automobile or the action of a fan, is not always satisfactory.

engine C to a heater D in the body from which heater the hot air can escape through a pipe E the end of which is provided with an exhauster M into which the pipe N leading fromlthe silencer I leads so that the gases as they escape from the silencer induce a current of air through the pipe A and heater D. The flow of air through the Ithas also been proposed to pass the ex- Q Q haust through a heater, but this system has the defect that should there be any leak the exhaust gases escape intothe body and also is below atmospheric pressure.

that there is frequently unpleasant noise and vibration. Moreover, there is the danger that should a back fire occur, the whole of the heater may be blown up. According to this invention I connect a heater to which heated air is supplied to an exhauster so that the pressure in the heater The withdrawal ofthe air from the heater by the exhauster may be aided by exhaust gases issuin from the silencer.

- y invention is illustrated by the accompanying drawings, Figure 1 of which shows an automobile fitted with my heating device, while Fig. 2 shows a modification. A is a pipe which surrounds the exhaust pipe 3 and leads from the neighborhood of the What I claim is The combination with the engine of an automobile, of a closed heater within the automobile, a pipe open. at the front and leading from the engine compartment or f casing to the heater, a pipe leading from the heater and delivering rearward beneath the automobile, and a pipe connected with the engine exhaust and injecting into the pipe,

leading from the heater, the organization being such that hot air from around the engine is led through. the heater without discharging into the interior of the automobile and is discharged from the heater by the injected exhaust gases entering the. discharge pipe from 'the heater.

In testimony that I claim 'the'foregoing as my invention, I have signed my name this sixteenth da of January, 1920. v A.. RIAN DENMAN-JONES.
